I just noticed the same thing on my goal of 2000k this year. It shows I've only run 21.7 so far, but all the other data seems to be fine. Were the other 800-odd kilometers too slow to be considered 'running?'

A bit of code that's still in development sneaked into the site update I made yesterday. Instead of rolling back the change, I patched it because it doesn't affect the website much. Let me know if you see any other problems.
